Rash/red spots on arm

[sanvers]

hey guys,
i’ve had pretty bad luck with my health recently. had an infected wisdom tooth which was solved with antibiotics and a pretty bad cold. three days ago i woke up and noticed a weird rash on my stomach and forearms and back. it hasn’t touched my legs. it’s not really itchy or raised and it presents as blemishes under the skin. i kind of ignored it until that same night, my cheek on the right side broke out in almost hives. went to the doctor the next day and got piriton and my face cleared up. my stomach is basically back to normal but the marks are still on my forearms. wondering if anyone could help identify or tell me why they’re taking so long to go away. the doctor didn’t seem to worried and said it was most likely an allergic reaction to something. i feel ok minus the rash. thanks!

Even with my brightness turned all the way up I can’t see what your talking about but if the dr wasn’t concerned upon seeing it then there is nothing to worry about.

Yeah, I can barely see the spots, they look like they're going way. It just looks like minor irritation, so I wouldn't worry.

On the bright side, you made me feel better about not being tanned

Trust the doc on this one not strangers on the internet who are unqualified
